Project Shotover Upgrade Reaches Another Milestone

Dec 18, 2013

Project Shotover has reached another milestone, with QLDC’s three preferred tenderers confirming that they will submit bids to upgrade the wastewater treatment plant. Project Shotover is one of the Council’s most significant infrastructure projects and the Council has budgeted $35.9 million for a staged upgrade of the plant over 13 years.

General Manager Infrastructure and Assets Erik Barnes said that the three consortium bids led by Downer Construction Ltd, United Group Ltd and WorleyParsons were tendering to design and build the upgrade, after successfully pre-qualifying for the bid process.

WorleyParsons has replaced  Infrasol as one consortium bid leader after Infrasol withdrew due to high workload commitments, with the other five companies in its consortium remaining the same.

Mr Barnes said that the consortium’s attributes had been re-evaluated based on WorleyParsons’ involvement and the reconfigured consortium still ranked among the top three bidders. As a result, its application to be included in the tender process had been accepted.

The purpose of stage one of the upgrade is to produce a higher quality treated effluent than the existing plant is currently able to deliver, in order to meet more stringent resource consent requirements, provide a higher level of environmental protection and cater for future population growth in the district.

Stage One involves the construction of a treatment plant for purifying the wastewater and removing solids at the site of the existing treatment ponds, on the Shotover delta. The plant will service Queenstown, Arrowtown, Frankton, Quail Rise, Arthurs Point and Lake Hayes.


The tenders close on 14 March 2014.
